Drafts affect infrared thermography results
Infrared thermography is extremely sensitive to even very gentle drafts, Austrian researchers have found.
A wind speed of less than 1 metre per second can cause a drop in measured temperature of about 0.6°C, while winds of 1.3-2.6 metres per second can cause a drop of 1.5°C. Winds of 3-4 metres per second can cause a drop of 2.1°C.
The researchers warned that the discrepancies were more than sufficient to lead to a wrong diagnosis.
One of the study’s authors, Simone Westermann, from the University of Veterinary Medicine in Vienna, said she was keen to note the relevance of her work for vets who worked on horses.
